Pump Lasers – Fiber & DPSS

What are Pump Lasers?

Fiber lasers, like all other laser systems, require an excitation source to pump energy into the system. This is done through optical fiber pumping, similar to how it is done in DPSS lasers. The main difference between the two laser types is the delivery method of the laser pumping source. This source is traditionally coupled into a large core fiber which is then fused into a double clad fiber. This double clad fiber is doped with the particular gain material of interest for that specific laser. The double cladding allows for the high-power multi-mode fiber to be guided into the larger outer core at the same time as the single mode laser builds up in the smaller inner core.

Depending on the gain material that the fiber is doped with, the absorption band may be wide, or narrow, which means that in some cases, traditional high-powered laser diodes are acceptable, but in other instances wavelength stabilized diodes are required. On this page, you will find a list of all of the fiber laser modules and pumping sources, including both wavelength stabilized and un-stabilized laser diodes.
